Network transmission system and method for transmitting data streams

The invention provides a network transmission system for transmitting data streams. The system comprises a plurality of routing nodes, a path management module, a data stream monitoring unit, a topologyexploration unit, and a data streammanagement unit. The path management module comprises a network monitoring unit used for monitoring the node states of the above routing nodes. The data stream monitoring unit is used for obtaining the data stream information of a data stream. The topologyexploration unit forms a network topology is formed according to the node states. The data stream management unit is used for adjusting a transmission path according to the data stream information and the network topology, and transmitting the data stream through the routing nodes. 种适用于传输数据流之网络传输系统，包括：多个路由节点；路径管理模块，包括：网络监测单元，用以监测上述路由节点之节点状态；数据流监测单元，用以取得上述数据流之数据流信息；拓谱探索单元，根据上述节点状态形成网络拓谱；以及数据流管理单元，根据上述数据流信息以及上述网络拓谱调整传输路径，透过上述路由节点传输上述数据流。
